From: Ian Campbell <ian.campbell@citrix.com>
Xen 4.2 become unsupported upstream in 09/2015 (see
http://wiki.xen.org/wiki/Xen_Release_Features). However as far as the
interfaces provided by the toolstack libraries go 4.2 and 4.3 are
indistinguishable.
Therefore drop support for Xen 4.1 and earlier which removes a whole
pile of compatibility code which makes future work (to use stable
library interfaces provided by upstream) more difficult. In particular
all supported versions now use a pointer as a libxc handle (4.1 and
earlier used an integer, resulting in various shim layers).
Also Xen 4.2 was the first version of Xen to formally support upstream
QEMU (as a preview) so that makes sense as a cut-off now.
This change drops all the configure-y and resulting ifdefs in a mostly
mechanical way. A follow up will refactor wrappers which are now
unused.

Now that 4.2 and earlier are no longer supported "xc_interface *" is
always the right type for the xc interface handle.
With this we can also simplify the handling of the xenforeignmemory
compatibility wrapper by making xenforeignmemory_handle ==
xc_interface, instead of an xc_interface* and remove various uses of &
and *h.

needs this so it can live with all the others.
